UNITED STATES PATENT OFFICE.

IETHOD OF MAKING HOUSEHOLD ARTICLES.

Application filed; January 15, 1926, Serial No. 81,581, and in GermanyOctober 10, 1984.

My invention relates to a method of making household articles, such asspoons and forks, and it is an object of my invention to make sucharticles in as few operations as possible. To this end, instead ofblanking the articles from plate, I forge them from round bars out tosize and, in this manner, the articles are finished in substantially twooperations instead of ten to twelve operations; as in the old method.

In the old method, a blank was punched from a plate of suitable metal oralloy, silver, German silver, etc., the size and configuration of suchblank being adapted to those of the finished article. 'This blank wasthen cold-forged and cold-rolled, with re eated annealingsfuntil it hadthe desired con guration, and then cut out and polished.

As the material is diflicult to machine, and the finished article, spoonor fork, is of complicated configuration, this method is performed inmany operations and is extremely difficult, besides requiring many toolsand labour.

In the drawings, which form a part of this specification and wherein forthe purpose of illustration is shown a preferred form of my invention,

Figure l is a view of the rod of copper alloy from which my processstarts, and which is cut from the rod of material in what I designate asthe first operation of my *method,

Figure 2 is a View of the blank after the '35 second operation when ithas been flattened to form the bowl of the spoon,

F' re 3 is a plan view of the spoon after the t ird and last operation,

Figure 4 is an edge view thereof,

Figure 5 is a view of the blank rod representing the first operation ofmy fork making process,

igure '6 is a new of the blank after the second oppration when it hasbeen flattened to form e prongs of the fork,

F e 7 is a plan view of the fork after the rd and last operation, and

Figure 8 is an edge View thereof.

In my novel method, the initial material is not plate but a, generallyround bar of a suitable alloy. out from the bar and forged hot into thedesired shape. This method comprises substantially only two operationsviz, flattening out the round bar for the bow or the prongs, as the casemay be, and forging the flattened portion into the finished shape. Thebur is then removed and the article 18 ready for the finishingoperations of pickling and polishmg.

In this manner, and by starting from a bar and forging hot, the sameresult. is achieved .in two operations as was achieved in ten to twelveoperations in the old method.

Obviously, the manufacture is muchich'eap ened and the output is farsuperior as.-.compared with the old method. Any alloy which is suitablefor hot. forg- Blanks of suitab e size are ing, may be used inconnection with my novel method. Obviously, such alloys must possess thestrength required and must not be attacked by acids and basic substanceswhich are constituents of food.

High-class brass with a certain percentage of nickel is particularlysuitable.

I claim:

- 1. Method of making spoons and forks, consisting in hot-forging from abar the bowl or prong portion in one operation, and forging theremainder and finish-forging the portion already forged, in the nextoperation.

2. The method of making spoons and forks consisting in hot forging froma one-piece bar of copper alloy t e owl or pron portion in oneoperation, and forging t e remainder and finish forgingthe portionalready forged in the nextoppration, the whole being accomplished withut a; single heatmg.
